Fast track completion of urgent typhoon damage recovery construction project is becoming crucial for the prevention of the secondary damage from the next year typhoon, prompt psychological stabilization of flood sufferers, the early recovery of damaged infrastructure condition and so forth. As the recovery learning process has been continued for last consecutive typhoons and experts suggested, the keys in attaining the goals of the project (preventative, sustainable, cleaner and fast tracking development) are found to be the early contracting and improved competencies in project management especially during the design phase. It can be presumed that the former is attainable through administrative supports in the form of government guidelines, but the latter necessitates more research efforts. In this regards, this study aims to find a way how to lift up the current level of project management capability facing ever changing project mangement environment of urgent typhoon recovery project. By comparing the current level of application of government guidelines in flooded districts and analyzing the time required for each phase from design contracting to construction starting, several reformative ideas are illustrated in association with the necessity of adopting CM method in the deign phase. It is highly expected that CM application in the design phase can be an effective alternative in overcoming current limits in improving the quality of the project and prevent the delay due to the lack of expertise and professional workers in the owner side.

This study seeks to examine current status and issues on primary education environment and teachers in Cambodia, a country that has a poor education environment and low educational achievement I analysed the features and limitation of education. Major findings revealed the primary school students' low accessibility on education and poor competencies and qualification of primary school teachers, which have hindered a quality of education in Cambodia. Central implications were produced to improve the quality of education and training system for primary school teachers. First, sustainability should be embedded from the initial design to the performance evaluation of the projects. Second, we should carry forward a customized training project that can meet the needs of primary school teachers in Cambodia. Third, the Education ODA project should be institutionalized into the national mechanism of the credit accreditation system, including the incentives of participating. Fourth, in-service training should ensure the inclusiveness and accessibility for the disadvantaged in remote areas. Fifth, short-term workshops for teachers should be avoided, but intensive programs including mentoring should be expanded. Finally, we should support the establishment of autonomous teacher- learning communities based on school level across the Cambodia, which could establish the social capital of the teaching profession in a long term.

과학 문명의 발달은 산업 분야뿐만 아니라 사회, 문화의 영역에 이르기까지 폭발적 발전을 가능하게 하였으나, 자연 환경을 함부로 파괴하게 되었고 인류의 삶의 터전을 회복불능의 상태로 만들어 인간을 포함한 모든 생명체의 생존을 위협하고 있다. 환경은 한번 파괴되면 이를 회복시키는데 많은 시간과 비용이 소요된다. 따라서 환경에 대한 인식과 지식 및 기능을 습득하고 올바른 태도를 기르는 환경교육이 절실히 요구된다. 그러나 현재 우리 나라 초등학교에서의 환경교육은 대부분 인지적 측면만을 지고하고 있어 환경보전 인식의 내면화를 위한 교수-학습 방법을 필요로 하고 있다. 최근 웹을 교육에 활용하는 다양한 방법이 시도되고 있으며, 특히 웹 기반 프로젝트 학습은 정보의 수용이 아니라, 학생들의 연구에 의한 학습의 개념을 도입하고 있어 교사의 지도에 의지하지 않고 학생들의 자발적인 노력으로 프로젝트를 완성해 가는 것을 가능하게 해준다. 본 논문에서는 웹 기반 프로젝트를 활용하여 개인 또는 학급내 및 타 학급간의 협력을 전제로 환경을 탐구하고 환경 문제를 발견하며 이를 해결해 나가는 환경교육이 가능한 시스템을 설계하고 구현하였다. 이러한 웹 학습 공간을 마련하여 학습자가 다양한 자료를 쉽게 얻을 수 있게 함과 동시에 상호 정보 교환을 통한 협력 학습을 함으로써 이들에게 자연의 소중함을 일깨우고 환경보전을 실천하는 기틀을 다질 수 있도록 하였다.

To improve construction productivity and quality, and to make the construction environment safe, a new system, Robot-based Construction Automation (RCA), is currently being developed in Korea. To determine whether RCA is an improvement over traditional construction methods (TCMs), an evaluation method, called the Performance Evaluation Index (PEI), is suggested for RCA. The PEI considers the relationships among the factors influencing the performance of the system obtained using the Delphi method and the analytic hierarchy process (AHP). As the evaluation shows, RCA is much better than TCM except for three factors: the rate of work success, quality improvement by learning experience, and construction duration.

In early 21st century, universities in Korea has been asked the new roles according to the changes of educational and social environment. With Korea's NURI and Brain Korea 21 project support, some chosen research oriented universities now should produce "teacher of teachers". We look 100 years back America's mathematics and see many resemblances between the status of US mathematics at that time and the current status of Korean mathematics, and find some answer for that. E. H. Moore had produced many good research mathematicians through his laboratory teaching techniques. R. L. Moore was his third PhD students. He developed his Texas/Moore method. In this article, we analyze what R. L. Moore had done through his American School of Topology and Moore method. We consider the meaning that early University of Texas case gives us in PBL(Problem Based Learning) process.

In the construction industry, professionals are required to have advanced problem-solving skills to adeptly handle the dynamic challenges inherent to project execution. These skills are crucial, as they enable professionals to effectively navigate the complexities and unpredictability of construction projects, ensuring timely and cost-effective completion. This paper explores an innovative approach to enhance the problem-solving skills of construction students through the integration of conversational AI-based serious games into their educational curriculum. The objective of this research was acquired by following three phases: hazard interaction, problem identification, and AI-guided text-based communication. This approach creates an engaging learning environment, simulating real-world construction challenges and problems, focusing on the excavation phase of a construction project as a case study for students to interact with and communicate with the Conversational AI agent through text-based prompts. In the future, the proposed study can be used to evaluate how AI agents can help enhance problem-solving skills by promoting emotional engagement among participants. This research sheds light on the potential of integrating conversational AI in education, providing valuable insights for educators designing construction management training programs by underscoring the importance of engagement in real-world problem-solving scenarios.
